Copyright and other intellectual exclusion (IE) laws were introduced in good faith to ensure that (1) it is rational to undertake intellectual endeavours and (2) the number of people who benefit from intellectual endeavours but don't support its development is limited.
Then the background against which IE had been written changed; now, some IE holders began to abuse their monopoly (a form of parasitic behaviour), and they came to informal understandings with lawmakers (who also put their own personal interests ahead of the collective interest, which is again parasitic) to strengthen the IE laws.
The real problem with IE laws is that as more people use intellectual works, the value to society increases, but due to the exclusionary nature of IE laws, they discourage widespread dissemination. The best solution would be a separate parallel economy for intellectual works where all consumers pay an amount from the primary economy that doesn't depend on how many intellectual works they consume, but producers receive an amount that depends on how much utility consumers directly or indirectly extract from their work (in proportion to all other intellectual works). That would open a number of difficult issues, and current parasites under the IE scheme have amassed enough power to resist it strongly, so I doubt we would see it any time soon even though it would be collectively beneficial.
Some chose not to cooperate, and ignore that. As long as they are not too numerous, the system as a whole does not break down. The majority pretends that IP is rival and excludable, so pay creators for their creations, and creators get paid roughly in proportion to the demand for their works, and thus creators tend to create the works that the consumers want.
DRM has been developed to attempt to limit the effects of the uncooperative, and the uncooperative have developed systems to try to make it harder to detect piracy.
